One of the problems is, (IMO) is that you can't have a sliding scale of punishment to cater for the severity of the murder/rape/chid abuse etc whereby one murder (and other heinous crimes) is deemed to be more severe than another if the penalty is death. I fully admit that if it was my daughter that suffered this despicable crime, the b@stard would be dead by my hands but to give legality to what is mob rule would be wrong. Like it or not, that is how society has evolved and any retrograde step would not serve us right.
As ExBay has already said we can absolutely have a sliding scale of punishment to fit the crime, we already do.
Individuals who commit the same offence can serve varying lengths at the judges discretion.
Also describing Capital Punishment as 'Mob rule' attempts to belittle what is a perfectly legitimate alternative form of punishment, such has been used by opponents of it for years.
It is not mob rule, it can be used dispassionately. It is a punishment meted out to those who have committed a certain level of criminality, not some sort of emotional hyperbole.
The important thing for me is that having capital punishment available does not mean we have to use it, it is an option available for the most heinous, grievous and most damaging of crimes.
Those that damage and sicken individuals and society to such an extreme that no other form of punishment is tenable.
Personally I believe that society is degraded by not having it available. It says of us that we value life above all things, that no crime or offence is to great that we won't accept it. We are all tainted by the individuals that commit these crimes, and are tainted even more so by the impotence and ineffectuality of our justice system to deal with these people.
An example is the execution of Saddam Hussein, a more deserving indivdual I would find hard to find.
His execution, sanctioned as it was by the Coalition forces, made me study my feelings on this very closely.
Here was a man being condemned to death for his crimes, his guilt was never in doubt, however I (even as a supporter of the death penalty) found it difficult to watch and accept. That said, I did watch and accept it.
To my mind, there was no punishment in British law that would have been satisfactory for this man.
His punishment was entirely appropriate and fully justified.
I'm sure there are very few people who feel in any way worse for the passing of this man. Iraq, even now, is a better place for his absence. There are many who suffered at his hand that can now continue their lives knowing that justice has been served and that he will never again be able to commit the same offences.
That is the essence of an effective death penalty.
